One way to answer questions like this is to count up the material each side has.
White has 8 pawns (+8), a queen (+9), two rooks (+10), a knight (+3), and a bishop (+3) = 33 points. Black has 7 pawns (+7), two bishops (+6), and two knights (+6) = 19 points.
So yes, 33 vs 19, White has a big advantage and should win easily.
Here is a game I recently accepted a draw on. I have only accepted one draw in all my games. And I was just curious to other opinons on whether I would have eventually won.
